Brief summary (registry, in English)
This study is a multicenter, ambidirectional cohort study aiming to consecutively recruit asymptomatic biliary dilation patients incidentally discovered by imaging from 25 medical centers across China. The investigators will collect comprehensive clinicopathological data from the cohort to evaluate the epidemiological characteristics of asymptomatic patients, the distribution of Todani classifications, common imaging-detected comorbidities, and natural history; and, based on high-quality evidence, assess whether surgical intervention can improve the prognosis of asymptomatic patients, thereby providing a basis for developing targeted surveillance and intervention strategies.
